Forgot to mention, this is a server crash.

msparkles · Answer 3 · 2023-01-22T03:54:24.000Z

Not that we think someone did, we don't think we even have a fake player block in the pack?..

Oh, we think we see it now.

We think your mixin applies to all and every time anything attacks anything, and the method fails when the attacker is null, which happens as long as there's a fake-player attacker, like Dark Utilities' plates.
